My son has been getting crank calls from someone blocking their number fom being seen. Instead of seeing the incomong phone number, it's just labeled 'Restricted'. Does anyone know how to stop the calls, or, at least, find out what the phone number is?

Sign up for TrapCall (google it). You can sign up for the cheapest plan which is below $5 a month. Sign up it for like a month then cancel after. Trapcall reveals the restricted number. You should see the phone number.

You can add usage controls to your account. This feature will allow you to block restricted numbers also. The feature is 4.99 a month. I have provided a link for more information. Click herehttp://search.vzw.com/?do=viewdoc&id=20989Hope this helps!
